I'm not an expert in CS (not even close), but to me it looks like there is very little crust on Apple technologies.
There is some, but not nearly as much as say what's in win32. This lack of 'crust' can be attributed to SJ's personality. He had no problems dropping something he didn't think worked. This led to headaches for 3rd parties, and is one of the primary reasons enterprise stayed away from Apple (along with no roadmaps).
How can you lead if you don't understand fully the field.
It's not so much that you need to understand every in and out of the field. What you need to understand is effort level required develop something[1], and when you're clearly getting BSed. How much technical knowledge you need to do those two things is the hard part to figure out.
[1] I once had a manager ask me why a change was going to take so long because she thought "it's just and if/then statement."

Those are not trivial things to do. Is not so rare for me to underestimate the effort required for a change in own code (but this might be because I'm not such a great programmer).
